I had fun with this. The only critiques that I have are 1) the batteries drain too fast and 2) some of the mechanics like crouching and jumping are a little off. I had to hit Ctrl then C in order to get into the vents and jumping onto crates felt a bit loose like I couldn't stick the landing and would slide off. Other than that, I like what you have going here and I look forward to playing the full game. Good job!
